Deputy governor Subhash Sheoratan Mundra said at the same event that financial institutions should collaborate on use cases."Cloud-based computing, blockchain processing technologies and virtualization of IT systems are a few examples which hold potential for being used in a big way ... Banks and IDRBT can work together to study these, test them out and adapt for best use."The Reserve Bank of India has been investigating applications of the technology, including the possible issuance of its own digital currency, since as early as 2014, according to reports at the time.
